Butyl Rubber Tape
Seals Without Curing
A butyl tape is not a mastic that hardens and cracks. It is a non-curing butyl rubber strip that stays tacky for the life of the roof: solvent-free, so it neither shrinks back from the edge nor off-gasses, and flexible enough to follow thermal movement instead of splitting. It bonds to metal, concrete, glass, timber and membrane, and doubles as a damper and a surface protector.

Where sealant tapes give up
Mastic dries out and cracks
Curing sealants harden, shrink and let go at the edge; that is the crack water finds. Butyl never solidifies, so the joint moves with the roof instead of opening.
Solvent tapes shrink back
A solvent-based tape off-gasses after it is laid, pulls away from the lap and leaves a gap. Solvent-free butyl does not shrink and emits no toxic gas.
Thermal movement splits the joint
A roof surface expands and contracts every day. A non-curing core absorbs that movement; a rigid bead fights it and loses.
It has to stick to what is there
Adhesion must work on the substrate in front of the crew: galvanised steel, concrete, glass, timber or membrane, clean or weathered.

Butyl Tape
Cailin Butyl Tape is a kind of lifelong non-curing self-adhesive sealing waterproof tape made of butyl tape as the main raw material, mixed with other additives, and processed through advanced technology. It has a good performance on the surface of various materials. Cailin Butyl Tape strong adhesion, and excellent weather resistance, aging resistance and water resistance at the same time, it can also play a role in sealing, damping and protecting the surface of the adhered object. Cailin Butyl Tape products are completely solvent-free, so they do not shrink or emit toxic gases. Because they do not solidify for a lifetime, they have a good resilience to the thermal expansion and contraction of the surface.
