Acrylic Siliconized Multi-Purpose

Description

Alucomex Sealer is a siliconized acrylic sealant in paste form that, once applied and cured, acquires a firm and elastic consistency.

Performance

A cartridge yields 5.69 m, in 7 × 7 mm joints, considering a 7% waste.

Usefull lifetime

12 months in a cool and dry cellar, in the original container at temperatures of 21 ° C and 50% relative humidity.

Advantages

  • Low VOC (Volatile Organic Compounds) content
  • It can be applied on slightly damp surfaces.
  • It is paintable (accepts all types of paint).
  • Excellent adhesion to porous or smooth surfaces.

Application

The surfaces to be sealed must be firm and clean, dry, free of dust, grease, oil, water and old sealant. Clean porous surfaces with a brush or by applying air pressure to remove all loose particles. In the case of smooth surfaces (such as glass, metal, etc.), cleaning is done with the two-cloth technique, which consists of wiping the surface with a cloth (lint-free) impregnated with isopropyl alcohol and immediately removing all impurities with another clean, dry cloth.

Place a masking tape on the surfaces to delimit the area to be sealed. Introduce Alucomex Sealer into the cartridge gun, cut the top of the cartridge. Then place the pipette and cut at 45 ° calculating the width of the joint to be sealed. Pull the gun trigger to depress the plunger and the product will flow over the joint. Apply the sealant in the form of a bead on the surface to be sealed. A minimum section of 7 x 7 mm should be left, a maximum of 10 mm.

Finally, a revision will be made in the opposite direction to the application, by means of a straight spatula to achieve the necessary penetration in the joint, a better adhesion and break the air bubbles that may be trapped during the application. At the end of the application, remove the masking, peeling off in the opposite direction to the application in a continuous but controlled movement. The excess can be removed as soon as possible with a cloth dampened with water.

Maintenance

  • It does not require any maintenance.
  • If the seal is damaged, replace the damaged section by cleaning the surface before applying the new sealant.

Recommendations

  • Carry out tests under real application conditions to ensure correct operation.
  • Do not apply to wet surfaces or materials in the process of curing or setting.
  • Paint it until completely cured.
  • Apply it in works less than 15 meters high.

Limitations

  • It is not recommended on surfaces that are in continuous contact with water.
  • In continuous traffic floor joints.
  • On galvanized sheet roofs.

Precautions

  • Sealant should not be applied to completely closed areas, as it requires relative humidity for vulcanization.
  • Uncured product may cause eye and skin irritation on prolonged contact. In case of discomfort, wash with plenty of water for 15 minutes and immediately go to the doctor.
  • Keep out of reach of children.
