Chemilink™ SS-236

Polymer Modified Repair Mortar for Industrial Surface

Chemilink™ SS-236 is a ready-to-use mortar made of graded silica sand, special cement, polymer and additives. It contains no calcium chloride or heavy metals. It is designed for high strength, long service life and easy application. It is a quality controlled high performance composition which will achieve high compressive strength and other various mechanical characteristics. The presence of a polymer ensures an excellent bond to most surfaces and enhances such properties in impermeability, flexural and tensile strengths. It is suitable for heavily trafficked areas such as highways where abrasion and impact resistance are required.

Functions

• To gain high mechanical strength within a relative short time;
• To maintain a long-term consistent performance; and
• To have excellent resistances to most known abrasions, and heavy as well as frequent impacts.

Applications

• Repairing of pavements of various concrete surfaces;
• Maintenance works of mechanical industries; and
• Protection of concrete against aggressive waters containing sulphates, sulphides, chlorides, etc..

Application Procedure

Surface Preparation

The surface of the area to be treated should be clean and free from dust, dirt, grease and/or other loose contaminants. Pressured washing is recommended for this surface cleaning task. All concrete substrates must be structurally sound and all cracks must be routed out and repaired with appropriate repair compounds. Once the area is clean, brush or roll Chemilink^TM SS-232 (primer) evenly onto the surface. Depending on the environment, it may take approximately 5 to 30 minutes for the primer to become touch-dry.

Once the area is clean, brush or roll Chemilink^TM SS-232 (primer) evenly onto the surface. Depending on the environment, it may take approximately 5 to 30 minutes for the primer to become touch-dry.

Note that the primer is designed to improve adhesion and impermeability; to prevent the coating material from debonding and to prevent pinholes on the finished surface. Use the original primer from the container – do NOT dilute; do NOT blend with any other product. Stir the primer contents well before use. The primer should be reapplied if the primer-treated surface is disturbed or it has been primed for more than 6 hours.

Under the conditions that the ground (surface to be treated) temperature is above 45°C, the surface should be wetted and cooled down to avoid flash set of the primer.

Mixing

When the primer is touch-dry, add approximately 6.0 L of water to a clean bucket or pail (capacity of 20 L), and then slowly add a 25 kg bag of SS-236 while it is being electrically stirred. Ensure 2 to 3 minutes of mixing time till the mixture is homogeneous and lump-free.

Note that electric stirring (mixing gun or other mechanical stirrer with rotation speed of ≥ 1,300 rpm) is highly recommended.

Thoroughly clean mixers and tools immediately after each batch to avoid material buildup. Use clean equipment for mixing. For any additional instructions.

Placing and Finishing

After mixing, place the mortar mix onto the primed surface; move it to position with an underlayment spreader. SS-236 may be placed for a thickness between 5 mm and 10 mm.

Curing

In hot and dry conditions, SS-236 should be cured with appropriate curing compound and the finishing surface is highly recommended to be treated with an appropriate sealant.

Usage and Coverage

The recommended thickness is 5 to 10 mm per layer. For placement of more than one layer, each subsequent layer should only be placed after the previous layer has been hardened (a minimum of 24 hours). One 25 kg bag of SS-236 yields approximately 0.0135 m³ or 13.5 liters, and cover approximately:

• ~ 2.7 m² at 5 mm thick
• ~1.35 m² at 10 mm thick

Package, Coverage & Shelf Life

Package : 25kg/bag;
Storage : 6 months life-span when stored in a dry and cool place.

Safety

Gloves and goggles should be worn. Any splashes to the skin or eyes should be washed off with clean water. In the event of prolonged irritation, seek medical advice. Powder products should be handled to minimize dust formation. Use a light mask if excessive dusting is unavoidable.
