TYPICAL PROPERTIES OF POLYMERIZED MATERIAL Polymerization 7 days at 23 ° C / 50% RH, on 2 mm thickness,: Physical Properties: Shore Hardness ASTM D 2240, Durometer A 22 Elongation, at break, ASTM D 412,% 500 Tensile strength , ASTM D 412 N / mm² 1.8 (psi) (260) GENERAL INFORMATION This product is not recommended for use with pure oxygen and / or oxygen rich systems and should not be used as a sealant for chlorine or other materials strongly oxidizing. For information on the safe use of this product, consult the Safety Data Sheet (MSDS). NOTES: The polymerization process can cause corrosion of some surfaces. Instructions for use 1. To obtain the best performance, the surfaces to be treated must be cleaned and degreased. 2. The polymerization by contact with the humidity starts immediately after the product is exposed to the atmosphere, therefore the pieces to be sealed must be joined within a few minutes after the product has been dispensed. 3. The adhesive must be allowed to cure (eg seven days) before subjecting it to heavy service loads. 4. The excess product can be easily removed with apolar solvents. NOTES: LOCTITE® SI 5940 ™ is not recommended for the cylinder head seal. Note The technical data contained in this document is intended as a reference.

LOCTITE® SI 5940 ™ Cures when exposed to moisture and produces a flexible, tough oil resistant gasket. This adhesive sealant is mainly used for general use, as a filler or to form gaskets on the spot. Adheres to clean metals, glass, silicone resins, vulcanized rubbers, ceramics, natural and synthetic fibers, in addition to many plastic and painted surfaces. This adhesive is normally used in applications where the temperature range from -50 ° C to 200 ° C and can intermittently reach temperatures up to 220 ° C. TYPICAL PROPERTIES OF THE NON-POLYMERIZED PRODUCT Specific Weight @ 25 ° C 1.02 Extinction Rate, g / min 200 Flash Point - See MSDS TYPICAL PRODUCT PROPERTIES: POLYMERIZATION Skin time Skin time is the time within which the adhesive forms the superficial skin when exposed to atmospheric relative humidity between 50 ± 5% at a temperature between 25 ± 2 ° C "time-skin", minutes 14 Tack Free Time The time called Tack Free is the time required to obtain a dry, non-sticky surface. Skin time, 20 minutes
