Building Sealant Main Base Material
Jan 23, 2016

Butyl rubber, acrylic, styrene-butadiene rubber,neoprene, silicone

Tung oil, linseed Oil PuTTY

Hot-melt-pitch-based series of oxidation andhardening of glass PuTTY

Silicone (remove acetic acid, alcohol, ketone,de n-type), polyurethane

Polysulfide rubber, silicone rubber, silicone,polyurethane modified

Characteristics of building sealant (advantages and disadvantages):

① the volume contraction;

II hardening time fixed-free strength andtoughness in retractable parts do not apply non-elastic (medium) is not suitable for use inretractable parts

Three parts, starting from the surfacehardening, easy construction;

④ curing speeds vary with different temperatureand humidity;

⑤ volume is small, easy to foaming

⑥ need mixing operation;

⑦ volume shrinkage;

H-cured more quickly;

Krispy Kreme temperature affects the curingspeed
