Butyl Liquid Rubber

Butyl Liquid Rubber is a specially formulated version of Butyl sheet rubber that has the flexibility needed for vehicles that are traveling and causing significant amounts of tension as it travels and turns.
Butyl Liquid Rubber is a liquefied version of a synthetic rubber typically referred to as Butyl.


Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" which butyl rubber is based. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene. Structurally, polyisobutylene resembles polypropylene, but has two methyl groups substituted on every other carbon atom, rather than one.
Prior to the liquefied version emerging on to the market, rolls of the rubber were used for waterproofing roofs. The liquids are much easier to apply. It can also fill-in cracks and crevices and form an entirely seamless membrane. Butyl Liquid Rubber can go where the sheet version could never effectively coat. Butyl Liquid Rubber coatings have more uses. Over the years they have been used for roofing, cooling tanks, industrial applications, storage tanks etc. They can be applied to a wide range of roofing materials including metal, fiberglass, concrete bur roofs etc. Always consult your roofer to determine if aftermarket coatings are acceptable given the condition of your overall roof.
