Coalescing Agents
Coalescing- or film forming agents are used in water-based coatings to decrease the minimum film forming temperature (MFFT) of polymer dispersions. We can offer two types of coalescing agents, the conventional non-VOC coalescing agent ADDAPTOL™ DB and the polymeric coalescing agent BioWet™ PC.
ADDAPTOL™ DB
ADDAPTOL™ DB is a non-VOC oxygenated solvent for use as a coalescing agent in water-based coatings. ADDAPTOL™ DB is also used in floor lacquers, coatings for concrete surfaces and other coatings where high performance is needed. Proprietary mixture of branched esters of dibasic acids.
Benefits
- non-VOC
- nearly odourless
- higher efficiency compared to typical coalescing agents
- early block, rain, and chemical resistance
- no labelling
- readily biodegradable
BioWet™ PC
BioWet™ PC is a non-SVOC polymeric coalescing agent for use as a processing aid in waterborne systems to improve film-forming properties by lowering the MFFT. Proprietary polymeric composition and amphoteric component emulsified in water.
Benefits
- shows good compatibility with dispersions based on pure acrylics, styrene/acrylics, vinyl acetate homo- and copolymers and alkyd emulsions
- lowering of MFFT
- non-SVOC
- nearly odourless
- excellent wetting and levelling properties
- improves wet scrub resistance
- improves mechanical properties
- improves early rain resistance
- post addition possible
- “winter-additive” for renders/plasters
Applications
- water-based coatings
- plasters
