Sauereisen Insa-Lute - Model No. 1 Paste & P-1 Powder -Adhesive Cement

Insa-Lute Adhesive Cement is also available in powder form known as Sauereisen Cement No. P-1. When mixed with water at the proper ratio, No. P-1 has the same characteristics as the No. 1 Paste.

Working properties of the cement exhibit a virtually unlimited pot life prior to exposure to air. This feature makes Nos. 1 & P-1 ideal for automated applications using dispensing equipment. Due to its inorganic composition, Insa-Lute Adhesive Cement is very stable and will neither outgas, nor cause skin irritations like many other adhesives.

Mixing

No. 1 should be thoroughly remixed to a smooth, uniform consistency prior to use. If necessary, Thinning Liquid No. 14 can be used where the cement is required in a more fluid consistency. Minimal amounts of extra liquid should be used as excess liquid will reduce mechanical strength, increase shrinkage and delay set time.

The mixing ratio of No. P-1 should include 75-80% Powder and 20-25% water, by weight. Mixing may be done with a slow-speed mixer or by hand with a spatula.

Application

Surfaces to receive the cement should be clean and free of grease and dirt. Porous substrates should be dampened slightly with Sauereisen Thinning Liquid No. 14 prior to application.

Sauereisen Insa-Lute Adhesive Cement Nos. 1 & P-1 are air-setting and should be used in thin applications. Avoid applying in a thicknesses greater than 1/4 inch. If necessary, multiple coats may be applied to build thickness. Placement of the cement may be done by brushing, dipping or spraying.

SETTING/CURING

Nos. 1 & P-1 cure by air drying at room temperature. Drying time depends on the consistency and thickness of the application. Normally 18-24 hours drying at ambient temperature is sufficient.

When the cement has limited exposure to air, or if it is desired to accelerate the cure, low temperature oven drying at 180oF can be used. Avoid steaming while drying. If the cement will be exposed to elevated temperatures that may approach or briefly exceed the recommended service limits, contact Sauereisen for appropriate drying schedule recommendations.

A heat cure is also suggested where humidity resistance is required. In addition, a moisture-resistant lacquer or silicone coating may be applied to the exposed surfaces.

PACKAGING

• No. 1: 1-quart and 1-gallon cans; 5-gallon pails.
• No. P-1: 1-quart and 1-gallon cans; 50-lb. bags on stretch wrapped pallets.

SHELF LIFE

When stored in unopened, tightly sealed containers in a dry location at 70oF, Sauereisen No. 1 Paste has a shelf life of six (6) months and No. P-1 Powder has a shelf life of one year. If there is doubt as to the quality of the material, consult Sauereisen.

CLEAN-UP

All equipment should be cleaned with soap and water before Nos. 1 or P-1 cure. If removal is required after cure, a low concentration of sodium hydroxide may dissolve the cement. Consult Sauereisen for other recommendations.

CAUTION

Consult Material Safety Data Sheets and container label Caution Statements for any hazards in handling this material.
