Frequently Asked Questions

Answers to the most frequently asked questions

General Questions:

  1. What is the correct coverage of adhesive?
  2. What kind of strength will I get?
  3. How are solids calculated for a contact adhesive?
  4. How is open time determined (or definition of open/ dry time)?
  5. Are there any STA’-PUT products with MIL specification testing?

Answers to the General Questions:

  1. For typical applications a coating weight of 2.5 – 3.5 dry grams per square foot is recommended. – see “Proper Coverage Pattern” for visual
  2. Strength differs with each adhesive and substrate combination.
  3. Solids of an adhesive is determined by weighing a given sample, before and after exposure in 275F oven, and calculating the remaining solids in the sample.
    (dry weight – tare weight)/(wet weight – tare weight) x 100 = Percent Solids
  4. See “Contact Adhesives Definitions”
  5. No, none have been certified to any MIL specs at this time.
