Bond strength is surfaces must be clean dry Initial tape application to Application Techniques dependent upon the amount and well unified. A typical surfaces at temperatures of adhesive-to-surface surface cleaning solvent is below 10C (50F) is not contact developed. Firm isopropyl alcohol & water. recommended because the application pressure Use proper safety adhesive becomes too firm develops better adhesive precautions for handling to adhere readily. However contact & thus improves solvents. once properly applied low bond strength. temperature holding is 3. Ideal tape application generally satisfactory. 2. To obtain optimum temperature range is 21C adhesion, the bonding to 38C (70F to 100F). Outdoor protection of metal No. 226 is used for masking Hot air levelling.
