Sealant relaunch

Geocel is relaunching an improved version of one of its most popular Dow Corning sealants – 794.

The new sealant, known as Dow Corning 799, includes some improved characteristics, including improved and advanced adhesion to PVCU.

The new Dow Corning 799 is a one-part, neutral curing clear sealant that is ideal for use with polycarbonate sheeting and as a perimeter pointing sealant for door and window frames. Because Dow Corning 799 has excellent weathering characteristics – including resistance to ozone, UV radiation and temperature extremes – and guaranteed no slumping, it will give a long lasting and high quality finish to any glazing application and will not experience any of the discolouration, or ‘yellowing’ issues common with many clear sealants.

Dow Corning 799 offers ± 50% joint movement capability, allowing for the expansion and contraction of glazing substrates and enabling it to cope with a wide variety of applications especially since it cures tack free in just two hours. It conforms to BS5889 Type A, the British Standard for low modulus silicone sealants.
