ITW Spraycore® SC 2045 Coring / Bulk Print Blocker
Categories: Polymer; Thermoset

Material Notes: SC 2045 is a uniquely blended compounded resin that can be used as a coring material or a bulk print blocker to enhance the cosmetic appearance, rigidity, and speed of production of fiberglass reinforced plastic products. When used as a fiberglass print barrier, SC 2045 is applied behind the "skin coat" laminate. It greatly reduces the transfer of the fiberglass pattern of the laminates behind the coring material onto the gel coat surface. MEKP catalyst is not included. Product features: very fast gel time and cure cycles, superior bulk print blocking properties, extremely rigid product, blue color helps reveal air bubbles. Product benefits: excellent choice for high speed production, greatly reduces fiberglass pattern transfer, improves impact resistance, reduces manufacturing costs, produces consistent and void free application. Preferred red dye catalyst: HP-90, HP 90.
