Renia Syntic is a polyurethane-based contact cement for bonding all materials associated with shoe making and shoe repair. Free of toluene and Methyl ethyl ketone (MEK).

Bonds all materials used for repairing and producing shoes and boots like leather, rubber, EVA, thermoplastic rubber (TR), expanded rubber, PVC (Vinyl) , felt, cork, transparent materials, Perbunan-N, nylon, and more. 

INSTRUCTIONS:
Grind all materials and remove all grinding dust and fibres. Coat both sides with Renia  Syntic until you can see a layer of cement. If necessary, apply a second coat to absorbent materials.

TR (Thermoplastic Rubber): Apply Renia-Rehagol and coat after 15 minutes with Syntic. PUR (Polyurethane): After grinding, press the material with absorbent paper to remove the water. Then coat it with a thin layer of Renia-Syntic to reinforce very soft polyurethane. Apply another layer of adhesive on top of the dried first layer if necessary.

OPEN ASSEMBLY TIME:
Depends on the material: 5 - 30 minutes (TR 3-15 minutes, PVC 10 - 45 minutes). Syntic can be dried with an infra red lamp: IR-Lamp 176 °F: 3 minutes.

PRESSURE:
15 - 60 psi depending on the material
15 psi minimum time 60 seconds, 45 psi minimum time 30 seconds
The softer the material the less pressure is needed. Reduce pressure to 15 - 25 psi for soft materials or air cushion soles. Caution: Do not deform materials during pressing, otherwise the adhesive film will be destroyed.

HIGHLIGHTS:
Because of the fast crystallisation and the high initial bond strength of Renia-Syntic, it is possible to handle the bonded pieces after a few minutes. The heat resistance is high enough to trim or buffer the sole or heel. The bonding strength increases continuously during the first two days. Although the plasticizer resistance is already extremely high as a one-component system, adding 5-10 % hardener further increases the resistance against heat, oil, and other chemical influences.

SHELF-LIFE:
Minimum 12 months at 68 °F
