B-853DV-LMM
Black Vinyl Ester Barrier Gel Coat
Technical Data Sheet
B-853DV-LMM is a low VOC vinyl ester barrier coat designed specifically for marine applications to provide superior water
permeation barrier between the gel coat film and fiberglass laminate. This product meets MACT Standard, EPA 40 CFR
Part 63 requirements of the National Emission Standards for Hazardous Air Pollutants: Reinforced Plastic Composite
Production, maximum of 48% HAP for corrosion resistant gel coat.
FEATURES BENEFITS
HAP content is a maximum of 36% Lower emissions in the shop
Unique vinyl ester polymer Superior resistance to osmotic blistering, cracking due to
impact and thermal cycling
High temperature capabilities Improved appearance of the gel coat surface
Excellent spray characteristics Minimizes equipment setup and adjustment time

Application: B-853DV-LMM is formulated for spraying as supplied. It is strongly recommended that the material be mixed
before use. Optimum application temperature is 65 F – 90 F (18 C – 32 C). Two coats of 8 to 10 mils each are
recommended to build to a film thickness of 15 – 20 mils (0.38 – 0.51 mm). This two-step process is necessary to avoid
porosity, solvent entrapment and sagging. Brushing is not recommended.
Vinyl ester barrier coats are not intended to be used as a cosmetic finish due to rapid polymer degradation under the UV
light. Failure to follow the recommendation may result in damage to the gel coat surface from oxidation and chalking.
Storage and Handling: B-853DV-LMM should be stored in closed, opaque containers at temperatures above 40 F (4 C)
but not exceeding 77 F (25 C). Do not keep gel coat near catalyst storage areas. To avoid decomposition, keep away from
direct sunlight and excess heat. Refer to the Safety Data Sheet for further details on safety and storage.
