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.
