Features & Benefits

CASE Ingredients Features
Product Benefits
  • The main applications for two-component coatings based on WANNATET® IT-170B are automotive OEM and automotive refinishing.
  • WANNATE® IT-170B works as assistant resin in alkyd spray coating system for its high drying speed. This kind of coating is widely used in automotive refinish and industrial coatings.

Applications & Uses

Properties

Physical Form
Solubility Data
  • WANNATE® IT-170B can be thinned in polar solvents such as esters, ketones and ether esters, e.g. butyl acetate, methyl ethyl ketone and methoxypropylacetate, as well as in aromatics.
  • Generally speaking, it has good compatibility with the solvents listed.
  • However, the solutions formed must be tested for their storage stability. Only PU grade solvents should be used (max.0.05% water, absence of reactive groups such as hydroxyl or amino groups).
  • WANNATE® IT-170B can be thinned to stable solutions with a minimum solids content of 20 % in xylene, toluene, naphtha 100 and aromatic hydrocarbon mixture thereof.
  • If prolonged storage stability of the thinned solutions is required, aliphatic hydrocarbons should not be added.
  • Since WANNATET® IT-170B has necessary compatibility with aliphatic, it can be added in coatings formulated with aliphatic solvents.

Regulatory & Compliance

Storage & Handling

Storage and Shelf Life Conditions
  • Store in a cool, dry, well-ventilated area. Keep away from incompatible materials and foodstuff containers. Store in original containers. Keep containers securely sealed. No smoking, naked lights or ignition sources.
  • Protect containers against physical damage and check regularly for leaks. Avoid reaction with water, alcohols and detergent solutions.
  • Some isocyanates react with water to form amines and liberate carbon dioxide.
  • This reaction may also generate large volumes of foam and heat. Foaming in confined spaces may produce pressure in confined spaces or containers. Isocyanates will attack and embrittle some plastics and rubbers.
  • WANNATE® IT-170B is sensitive to moisture and must be stored in tightly sealed container. It can be stored for 6 months at temperatures between 0 and 30 °C.
