Sika presented new resin technologies that provide advanced UV protection for seamless floor systems. Four technologies were introduced: 1) Sikafloor 33NA PurCem, an aliphatic polyurethane/cement top coat that allows light colored screeds while maintaining thermal shock resistance. 2) Sikafloor 217 and 510N LPL, epoxy and polyaspartic resins with improved UV resistance for use in decorative flooring. 3) Sikafloor 315N, an aliphatic polyurethane top coat with UV blocker technology. 4) Sikafloor 510N LPL, a polyaspartic resin for use in decorative flooring with improved UV resistance.

- 25. Epoxy vs. Polyaspartic ? Web Search this question? You will find thousands of comments and opinions… Every product or resin technology has advantages and limitations… No single product or technology is best for every application. Example: chemical & stain resistance varies widely by specific formulation; not just the type of generic resin in the product… A full line, full service manufacturer will take the time to know a client’s specific requirements then recommend the best solution
