When & Why To Use High Temperature Masking Products

Masking Products are used for a whole host of different applications and reasons, varying depending on the industry in which they are operating. Below are some of the most commonly occurring reasons behind the use of advanced masking solutions.

To increase efficiency

Certain products such as Tape Dots work well to reduce the time taken to mask off menial area’s such as bolt holes, helping to increase efficiency when used over an extended period. Increasing efficiency is essential to completing work on time and turning around more projects.

To decrease costs

Similar to increasing efficiency, some masking products can be used in a cost effective manner to reduce the overall costs experienced with consistent projects. Products such as Silicone Caps & Plugs can be used multiple times before they are no longer effective, removing the need for constant replenishment of stock.

To provide a higher quality finish

When used for jobs such as Powder Coating our masking solutions can be used to provide a higher quality finish, such as to prevent over spray or coating of area’s which aren’t required. Masking Tapes are generally recommended for such uses, to reduce the need for secondary processes.

How To Measure Up For MaskingMasking Preparation

As the applications masked off can vary so greatly, it is generally recommended to have a selection of different sizes available to use at your disposal. Often, products such as Masking Tapes can be cut to a specific shape as covers for excess holes and gaps which may have been unforeseen during the initial masking procedure. For the most part the majority of our High Temperature Masking solutions can be used across a selection of hole and stud sizes.

Please see the table below for a guide on matching up our products to specific hole sizes, in particular threaded holes which are an extremely common application for our masking products.

Along with measurement considerations, it is important to take into account the temperature resistance required for your use. Temperatures of 200C°+ are generally recommended as industry standard for most curing methods, with both higher and lower temperatures also used for particular applications. To get an understanding of the different resistances available throughout our product range, please see the table below which outlines the majority of common solutions.

If hanging is a requirement during your masking/finishing process, then it is important to consider the weight ratings involved. Metal Hooks called ‘Paint Hooks’ are regularly used for such employments, coming in C, V & S styles suitable for varied uses. See the table below for an idea around the weight capabilities according to the chosen style.
