The following characteristics of coatings based on Enviroseal Wood-Gard™
were determined in laboratories and limited exposure studies.
Formulation Constants
- Theoretical Non-Volatile Solids
25%
- Theoretical Density, Lb./U.S. Gal. 8.5
- VOC
~70 grams/liter
Resistance to Water Blushing
Clear films of Wood-Gard™ display excellent resistance towards
water blushing in comparison to leading commercial acrylic and styrene/acrylic emulsions. Not only do the
clear films based on Wood-Gard™ show a minimal amount of film blushing under both ambient (250c)
and elevated (450c) water soak temperatures, but they also completely recover to visually clear
films when the water is removed.
Low Water Pickup
Wood-Gard™ also has excellent resistance properties, showing low
clear film water pickup. (Low water swelling)
Block Resistance/Low Coalescent Demand
Wood-Gard™ has shown an exceptionally high degree of early block
resistance, even when compared to harder polymers. Because of its high coalescent level, Wood-Gard™
has the ability to achieve a higher level of block resistance while lowering the VOC content to below Federal
Standards as Published by the EPA.
Exterior Weather-ability
Based on current exposure data, Wood-Gard™ has excellent exterior
weather ability resistance. Wood-Gard™ has been formulated for use in areas where there is
High UV and Enviroseal has enhanced the natural qualities of acrylic compounds to provide at least a three-year
effective life.
Reduced Water Vapor Permeability
Wood-Gard™ helps protect the substrate from moisture because of
the low water vapor permeability. This is an important factor to consider in the application to high humidity
where the existence of water and water vapor play a role in the efflorescence resistance of the finished
project.
Typical Wood-Gard™ Applications
- Primers
- Interior/exterior clear sealers
- Pigmented Sealers
- Curing Membrane
