Diamondhead USA White Paste Hardeners:
BPO Paste hardeners are for our polyester and acrylic based adhesive products. Available in 1 oz and 4 oz tubes. This white paste serves as the catalyst that accelerates the chemical reactions (CANNOT BE USED WITH WATER CLEAR POLYESTERS!).
MEKP liquid hardener is used for the Diamondhead USA Waterclear Polyester adhesive for white marble.
This type of hardener makes sure that the glue does not bleed and stain the white marble like regular polyesters do.
