About the product
Product Overview
SP-20 is a flexible aromatic urethane that has extreme tensile strength with an A shore hardness of 75. It is easy to install, has little odor and has elongation of over 1000%. It far outperforms epoxy membranes in crack-bridging and as a waterproofing membranes under Polymer Nation floor systems.
Uses
SP-20 is primarily used as a membrane in parking decks and waterproofing applications. It can also be used as a flexible broadcast resin, as a binder in flexible floor applications and bulked up using fumed silica to make a flexible patching paste.
Preparation
The coating installer should fully read and understand ICRI310.2R-2013 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer. If unsure as to the level of preparation needed contact Polymer Nation at techservice@polymernation.com
