BlastSkin II – Mine Safety
Quick Overview
BlastSkin II- Mine Surface Protection System is a very strong super-polymer coating system designed to provide structural support while shielding against water and methane infiltration for all surfaces in the mine. This system provides high chemical, abrasion resistance, low fire and smoke meeting Class 1 ASTM E84, MSHA ASTM E162, Radiant Panel testing and MSHA IC-249 Flame resistance of solid products. The BlastSkinII protection system effectively delivers increases load bearing capacity and reduces localized failure points to defend against rupture and bursting. This high-strength composite structure provides added protection to mine workers, framework infrastructure and overall mine safety.
Mine Surface Protection System:
- Inject LeakStop into all surface cracks and voids.
- Spray structural FireSkin™ Foam (10 pcf) on mine surfaces (25mm).
- Apply BlastSkinII super-polymer over the structural FireSkin Foam (3mm to 6mm).
- Apply GlowSkin striping to walls (0.5mm).
Technical Application Data
BlastSkin II is a two component 100% solids formulation which does not contain VOCs. Skin thickness has no limitation. BlastSkinII must be applied using a 2-component 1500-1800 psi high-pressure liquid pumping heated spray machine. Material and line temperatures may vary but usually initially targeted at 140°F. Thorough mixing of the B-Side component is required during application. Proper safety wear is mandatory. Surface application temperature ranges from 0°F to 150°F with surface dry. Spray cure time 2-5s. Surfaces must be prepped for cleanliness and dryness and requires the use of an adhesion promoter primer to acquire proper adhesion. Functional material operation temperature ranges from -40°F to 250°F. Final top-coat appearance is glossy and slick to the touch. This material will not flow-out or lay-down. Spray coverage at 16 mils is 100 sq. ft./ mixed gal thickness.
