K-FLEX APPLICATION MANUAL

USING PRODUCTS AND ACCESSORIES

CLEANING SURFACES

The surfaces to be glued must be perfectly clean and free of grease (use K-FLEX thinner). Ensure that the surface of the K-FLEX insulating material is also clean, otherwise it will not stick properly.

COATED SURFACES

Where surfaces have previously been painted, ensure that the glue is compatible and will adhere to the pant. Do not use the glue on surfaces that have been treated with products containing asphalt, bitumen or linseed oil. Use only chrome-zinc inhibitors and removal.

USING THE GLUE

Preparation and storage. Before use, stir the K-FLEX glue thoroughly.
To store the glue, close the lid tightly to prevent the solvents evaporating
If the glue should become too hard (eg. when stored in contact with the air), dilute with K-FLEX thinner. At low ambient temperature, don’t dilute but heat it up to approx 200c.
Method of application. When using a large quantity (eg. a tin of 2.6 litres), pour a small amount out into a separate container and top off when necessary. When applying K-FLEX insulation to metallic or other surfaces, the glue must be applied to the insulting material then to the corresponding surface.
Conditions for use. Do not apply to systems that are in use.
Do not use in sunlight. Weather protect where is possible.
The insulation should be left to dry for 36 hours before tuning the system back on.
The ideal working temperature of the glue is +200 C.
Do not use the glue at temperatures below +50 C as drying times are excessive.
At temperatures above +300 C, the glue dries very rapidly.
Dilute K-FLEX glue using K-FLEX Thinner only.
In case of spray application, dilute K-FLEX glue up to max 5%

HARDENING TIME: 36 hours
STORAGE: in cool conditions, away from cold and heat
SHELF LIFE: one year
QUANTITIES USED: with insulation sheets, approx 7m² per litre

CHOOSING K-FLEX' INSULATING MATERIAL

Before starting, choose the right type of K-FLEX insulation for the parts to be lagged. Use the thicknesses and sizes which are most suitable for the individual parts d the installation.

Don't forget - your dealer can give expertise advice.

USING K-FLEX' INSULATIONG MATERIAL

Insulating tubing that is oval or flattened (eg. the large cross-sections) should be cut along the flattened surface

USING REFRIGERATION PLANTS AND AIR -CONDITIONING SYSTEMS

- Treat steel surfaces with rust inhibitor prior to applying insulation. The paint should be left for a minimum of 24 hours to dry.
Take special care over gluing critical areas such as curved sections, flanging and support brackets. Ensure that the eras of the insulating material are always firmly attached to the piping.
- Do not apply insulation where parts are too close together, as this will result in the insulation becoming squashed and losing some of its properties. When carrying out particularly complicated installations on nickel steel, refer to our Technical Office.

TOOLS

A selection of good tools is essential for carrying out jobs to the highest standards.

  RIGID AND FLEXIBLE TAPE MEASURE

  Measuring and tracing lines to cut

  CHALK AND COMPASS

  To draw reference lines for measurement and cuts

  METAL BAND

  To help cut insulating sheets at the end of large diameter pipes

  CUTTERS AND KNIVES

  Use both long and shirt bladed knives, with spare blades

  BRUSHES (VARIOUS) AND FLEXIBLE SPATULA

  For spreading glue and painting

  SCISSORS

  To facilitate cutting insulating material
