There's a question that comes up on almost every R&D team's desk in the paint and coating industry: why do two formulations with identical resin and pigment compositions produce such dramatically different surface performance — one perfectly smooth and glossy, the other speckled and wavy?
The answer almost always comes back to the choice of additives. In the global paint and coating industry, one name consistently stands out as the technical reference point: BYK-Chemie GmbH.
As an authorized BYK Additives distributor in Indonesia, Jayawarindo provides access to the complete BYK additive portfolio for the paint, industrial coating, wood coating, and automotive coating industries. This article serves as a technical guide for R&D teams who want a deeper understanding of each BYK additive category and how each one contributes to the final formulation quality.
BYK-Chemie: More Than Just a Name in the Additives Industry
BYK-Chemie GmbH is a German specialty chemical company founded in 1962, part of the ALTANA group. Over more than six decades, BYK has built a reputation as a global leader in additives for the coating, printing inks, and plastics industries.
What sets BYK apart from generic additive manufacturers is the depth of scientific thinking behind every product. These aren't just formulations that "work" — they're additives engineered with a full mechanistic understanding: from pigment-polymer interface interactions and surface tension dynamics, to the complex rheology of coating systems.
BYK's product portfolio spans seven major categories, all directly relevant to the coating industry: wetting & dispersing additives, surface additives, defoamers & air release additives, rheology additives, adhesion promoters, wax additives, and UV absorbers.
Seven BYK Additive Categories and Their Role in Paint & Coating Formulation
1. Wetting & Dispersing Additives (DISPERBYK Series)
Wetting and dispersing agents are BYK's most widely used additive category and are often the first area evaluated when developing a pigment-based paint formulation.
The technical problem they solve
Pigments — particularly organic pigments with sub-micron particle sizes such as carbon black, phthalo blue, and quinacridone — have a strong tendency to agglomerate due to van der Waals forces and electrostatic interactions. Without the right dispersant, this agglomeration causes flooding and floating, loss of gloss, and colour instability between production batches.
How they work
Wetting agents lower surface tension to speed up pigment wetting by the liquid medium. Dispersants — typically polymers with pigment-anchoring functional groups — adsorb onto the pigment surface, creating steric or electrosteric stabilisation that prevents re-agglomeration.
BYK reference products:
- DISPERBYK-2155 — for solvent-borne systems; highly effective for organic pigments and carbon black.
- DISPERBYK-190 — for water-borne systems; a non-ionic polymer dispersant suitable for a wide range of pigment types.
- DISPERBYK-110 — for solvent-borne and solvent-free systems; recommended for titanium dioxide and inorganic pigments.

2. Defoamers & Air Release Additives — BYK Defoamer
Foam and entrapped air are two distinct technical problems that often appear together during paint production — and BYK has purpose-built solutions for each one.
A critical technical distinction
Macro foam consists of large bubbles that form at the surface during mixing — relatively straightforward to deal with. Micro foam is a different challenge: extremely small bubbles trapped inside the coating film after application, far harder to eliminate, and the primary cause of pinhole and crater defects on dried coating surfaces.
As an authorized BYK supplier in Indonesia, Jayawarindo stocks the complete BYK defoamer range across all major coating systems:
- BYK-1790 — VOC-free silicone defoamer for aqueous systems; ideal for wall paints, industrial coatings, and printing inks.
- BYK-054 — silicone defoamer for pigmented aqueous systems; highly effective against micro foam.
- BYK-088 — silicone-free and VOC-free polymer defoamer for solvent-borne, high-solids, and UV-curable systems.
- BYK-141 — defoamer for solvent-borne and solvent-free systems; compatible with both PU and epoxy coating systems.
Technical note
Defoamer selection must account for compatibility with the resin system. An incompatible defoamer can actually cause craters — a counterintuitive outcome where adding the defoamer makes surface defects worse, not better. Always run compatibility testing at lab scale before moving to production.
3. Surface Additives — Leveling, Slip, and Anti-Cratering
Surface additives control the final surface properties of a coating — and in the paint industry, the finished surface is the first thing customers see and judge.
Three primary functions of BYK surface additives
- Leveling — smooths the coating film during the drying phase by uniformly reducing surface tension, eliminating brush marks and orange peel effect.
- Slip & Scratch Resistance — lowers the coefficient of friction of the cured coating surface; critical for furniture coatings, floor coatings, and packaging.
- Anti-Cratering / Substrate Wetting — ensures the coating wets the substrate uniformly, preventing fisheye and cratering — especially on low-energy substrates such as plastics.
Reference products:
- BYK-302 — polyether-modified siloxane; a versatile surface additive for both solvent-borne and water-borne systems with excellent leveling and slip performance.
- BYK-378 — surface additive for aqueous systems; delivers excellent substrate wetting and leveling; PFAS-free.
- BYK-392 — acrylic copolymer leveling agent; non-silicone; combines leveling and defoaming in one product for solvent-borne systems.
4. Rheology Additives (RHEOBYK Series) — Flow Control and Sag Prevention
Rheology additives govern how a coating flows during production, storage, application, and drying. This is technically the most complex category, because each stage of the process calls for a different rheological profile.
The competing rheological demands within a single formulation:
- Low viscosity during application (spray, roll, brush) — so the coating spreads easily and evenly.
- High viscosity immediately after application — to prevent sagging on vertical surfaces.
- Sufficiently low viscosity during film formation — so leveling can occur before the coating sets.
- Stable viscosity during storage — to prevent pigment settling and maintain batch-to-batch consistency.
RHEOBYK products are available in multiple mechanisms — from organophilic clay (the CLAYTONE series) and urea-modified rheology additives to associative polymers for aqueous systems — giving formulators the flexibility to match the right solution to each specific rheological challenge.
5. Adhesion Promoters — Bonding to Difficult Substrates
Low surface energy substrates — PP, PE, and TPO plastics — present a real adhesion challenge in the coating industry. Without the right adhesion promoter, a coating that looks visually flawless can still fail a cross-cut adhesion test.
BYK offers adhesion promoters based on organofunctional silanes and specialty polymers that create a chemical bridge between the coating and the substrate — improving adhesion without requiring a complete reformulation of the entire system.
6. Wax Additives — Surface Protection and Matting
BYK wax additives — available in water-borne dispersions, solvent-borne dispersions, and micronized powder forms — are used to improve scratch resistance, abrasion resistance, matting effect, and surface feel in the finished paint.
Choosing the right wax requires careful consideration of binder system compatibility, its effect on the final gloss level, and application conditions. BYK's portfolio includes various grades of polyethylene, PTFE, and natural waxes to cover the full range of requirements.

Conclusion: The Right Additive Is an Investment, Not a Cost
In paint and coating formulation, additives typically account for just 1–5% of the total composition — yet their influence on the final 80% of product quality far exceeds their volumetric share. Surface defects, batch-to-batch colour inconsistency, and adhesion failures that turn into customer claims — nearly all of it can be traced back to an additive that was poorly chosen or incorrectly dosed.
BYK Additives aren't off-the-shelf commodities — they're formulation systems that require genuine technical understanding to use well. And that technical understanding starts with partnering with a distributor who doesn't just sell the product, but actually understands what you're formulating.
Jayawarindo, as an authorized BYK distributor in Indonesia with more than three decades of track record, is committed to being a long-term technical partner for Indonesia's coating industry — not just a raw material vendor.
