摘要:
Dry-to-the-touch compositions containing a polymeric matrix and a anaerobically curable component present within the polymeric matrix are disclosed. In a particularly desirable form, the compositions are moisture curable. The compositions are non-flowable, at high temperatures, and have an improved solvent resistance once cured.

Dry-to-the-touch compositions containing a curable polymeric matrix and a curable anaerobic composition present within the polymeric matrix are disclosed. In a particularly desirable form, the compositions are moisture curable. The compositions are non-flowable at high temperatures and have an improved solvent resistance once cured.
摘要:
The present invention generally relates to anaerobically curable compositions of: (a) a cyanate ester compound having the structure of formula I: R1O—C≡N)m (I) wherein m is from 2 to 5 and R1 is an aromatic nucleus-containing residue; (b) a (meth)acrylate monomer; and (c) an anaerobic cure inducing composition comprising peroxide and saccharin, wherein said composition is free of added metallic catalyst.
摘要:
An anti-seize composition which is non-flowable and dimensionally stable at temperatures greater than about 120° F. and dispensable at room temperature without the application of heat is provided. The composition includes a solid anti-seize lubricant, such as of metallic copper, metallic nickel, metallic aluminum, metallic lead, metallic zinc, graphite, calcium oxide, calcium carbonate, calcium fluoride, calcium stearate, lithium, molybdenum disulfide, boron nitride, barium sulfate. or combinations thereof. The anti-seize lubricant is dispersed in a carrier which is a solid at about room temperature. The carrier includes a grease with an ASTM D 217 penetration at 25° C. from about 200 to about 400 mm, a matrix material, and a naphthenic petroleum oil having a viscosity of less than about 300 SUS at 100° F. and having an API gravity at 60° F. from about 23 to about 25. The matrix material is a polymeric material. Optionally, a refined petroleum wax may also be included.
