Coalescing Agents
Coalescing- or film forming agents are used in water-based coatings to decrease the minimum film forming temperature (MFFT) of polymer dispersions. ADDAPT offers two types of coalescing agents, the conventional non-VOC coalescing agent ADDAPTOL™ DB and the polymeric coalescing agent BioWet™ PC.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 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
