Dowsil 888

DOWSIL 888 Silicone Joint Sealant is a one-part, non-sag silicone material that cures to a low-modulus silicone rubber upon exposure to atmospheric moisture. It can be used for concrete to concrete pavement joints, road pavement and general construction joints. It is ideal for use in new construction, repair or remedial applications. 888 Silicone Joint Sealant may be used to seal joints that are not uniform in width provided the movement capability of the sealant is not exceeded. May also be used in joints with minor spalling. DOW 888 Silicone Joint Sealant can be applied over a wide temperature range.

Colour: Grey, 16 per Box.
