Car lamp desiccant Professional desiccant for car lights

Product Introduction

The car lamp desiccant is made of high-purity magnesium chloride as raw material. It has stable chemical properties, balanced absorption performance, and high moisture absorption rate. In a high humidity environment (40 ℃, RH=90%), the moisture absorption capacity can reach up to 220%, and after absorbing moisture, it becomes a solid without any liquid water seeping out from the surface. The outer packaging is made of 3-layer leak proof packaging material, which firmly locks in moisture and does not penetrate.

Product Description

Product Feature

 2 options: fast suction type/slow suction type

There are 2 types of car lamp desiccants: fast suction type and slow suction type. You can choose the appropriate desiccant according to the humidity in the car and customer preferences.

Comparison of moisture absorption between fast-absorbing and slow-absorbing desiccants

❈The data test comes from the laboratory, the test conditions are: temperature = 40℃ RH = 90%, this data is for reference only

High hygroscopicity, complete moisture absorption

The headlight desiccant is a predatory chemical hygroscopic agent. As long as there is moisture in the air, it can be preyed upon. With an appropriate amount, the moisture in a specific space can be completely absorbed. At the same time, the rapid moisture absorption speed can quickly reduce the humidity of the space environment to the ideal humidity, creating a suitable dry environment.

High moisture absorption rate and significant moisture absorption effect

Magnesium chloride desiccant has stable performance and strong hygroscopicity. As the humidity increases, the adsorption capacity becomes stronger, and at the same humidity, the hygroscopicity is stronger than ordinary desiccants. And in an environment with temperature = 40°C and RH = 90%, the moisture absorption rate is as high as 220%.

Curing reaction, moisture absorption is irreversible

The moisture absorption of car lamp desiccant is irreversible. It locks part of the absorbed moisture in the form of crystal water through predatory chemical moisture absorption, and the other part participates in the curing reaction and is converted into solid matter. Once the moisture is absorbed, it will not be released into the environment, and a stable dry environment will be maintained for a long time.

Experimental testing：Solidifies and prevents leakage after moisture absorption

It is in powder form before moisture absorption, and gradually solidifies into blocks after moisture absorption. It has no fluidity. Even if it is squeezed and deformed by external force, it will not leak liquid, making it easy to identify whether it is effective.

High temperature resistance, no penetration

The car lamp desiccant can withstand high temperature working environment. It uses 3 layers of anti-leakage packaging material. The bag will not break after being exposed to 180° high temperature for 1 hour. It has the properties of waterproof, breathable, strong, tear-resistant, etc., firmly locks water and is impermeable.

Instructions for use

Instructions for use of car lamp desiccant, for reference only

① Keep the surface of the item dry and clean, without residual debris, stains or other dirt.

② Some headlight back covers have a special place for desiccant, which can be placed directly. (If not, you need to open the back cover of the headlight and put the product in).

③ Under normal circumstances, it will be damp in about 6 months. When the desiccant is completely solidified and agglomerated, please replace it in time.

Tips: The usage is 100-200g/m³. The specific time is related to the sealing of the car headlights and the environment in various places. The usage can be increased or decreased according to the actual packaging environment.
