Octocure 803 Zinc oxide Tiarco Chemical Catalysts / Accelerators / Vulcanizing agents >> Zinc Oxide Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE Octocure 803 zinc oxide dispersion is readily incorporated directly into latex emulsion compounds. Zinc oxide is a commonly used ingredient for the pigmenting and vulcanizing of latex rubber. Normal use level is 1.0 - 4.0 parts per hundred in SBR and Natural latex. Octocure 803 is based on French process zinc oxide having a surface area of 8 to 10 m2/g. Aqueous dispersion of zinc oxide. Used as vulcanizer in latex emulsion compounding for adhesive applications. Use level: 1.0-4.0 parts per hundred.
