- 0.35 - 1.4 wt%
- Application
- Coatings, Adhesives & Inks: Will improve adhesion to all metals with acccompanying improved salt fog resistance, reduction of creep at the scribe, and reduced blistering, and improved adhesion to ceramics, concrete, wood and plastics (except untreated PP/ PE). In WB exterior primers and deck stains, will eliminate peeling on wood substrate. In foundry cores, will improve bonding between sand and phenolic, urethane and similar binders.
- Water-Borne Coatings: For acrylic, styrenated acrylic, phenolic, PUD and alkyd coatings having pH 7-11. Use level 0.35 - 1.4 wt per cent on polymer solids.
- 2K Epoxy and 2K Urethane: Always add to hardener (epoxies) or polyol (urethanes). Use leve l0.35 - 1.4 wt. per cent on polymer solids.
- Urethane modified nitrocellulose: Add with Cowles-type mixing for 10 minutes. Use level 0.35 - 1.4 wt per cent based upon binder solids.

Technical Details & Test Data
- Procedure
1. Water-Borne: Post add at 0.35 - 1.4 wt% on polymer solids. Mix with conventional paddle-type mixer.
2. 2K Epoxy and 2K Urethane: Optimum performance is achieved when added to the hardener (epoxies) or polyol (urethanes). Product must be high shear mixed with a Cowles type mixer. Milling alone is not sufficient. Use Level 0.35 - 1.4 wt% on polymer solids.
- Product Performance
WB Bonding to Vinyl Flooring/ Carpeting with WB Acrylic
Commercial WB acrylic flooring/ carpeting adhesive. Bond assembly consisted of vinyl flooring to plywood. Adhesive allowed to fully dry for 72 hours at ambient temperature and water soaked for 168 hours. Control on left: failure mode is adhesive failure.
On right: 0.35% Chartwell C-515.71HR post-added to adhesive. Failure mode is now COHESIVE FAILURE ONLY. The adhesive strength to both vinyl and plywood is greater than the cohesive strength of the adhesive.
Adhesion of Polyester Baking Enamel on CRS
Conclusions:a
1. Without adhesion promoter (control>50% of coating removed
2. Addition of D-525.31 to the grind stage sharply reduces coating removal as follows:
Control – 50%
2phr – <1%
3phr – 0%Current recommendations: C-515.71HR, C-515.71HRX
3. Excellent humidity and salt-fog resistance
