## Overview

SeaDry Antihumidity Desiccant sachets use a high-performance calcium chloride and modified starch formula to absorb over 0.25 liters of moisture per pack, reducing relative humidity by up to 50%.

## Description

SeaDry Desiccants are high performing moisture absorbers/dehumidifiers which offer long lasting protection against condensation. SeaDry products reduce relative humidity levels by up to 50% significantly minimising the risk of condensation and moisture damage. SeaDry is primarily used for cargo transport and storage but can also be used around the home and in cars, garages, storage units, caravans and boats. The pouches contain a mixture of Calcium Chloride(Salt) and Modified Starch. Moisture is absorbed through the moisture permeable yellow topside which immediately binds to the salt and modified starch to form a gel eliminating any liquid. This combination is proven to be more effective than silica gel and desiccant clay. The outer packaging of the pouches are made from a PA/PE film and a Tyvek tear resistant material ensuring no leakages. Desiccants are sold in 5 variations : Single 125g, Strip 750g, Hook 600g, Pole H 1200g and Blanket 1500g Please note: Keep out of reach of children.

## Features

- HIGH PERFORMING MOISTURE ABSORBER – Made from calcium chloride and modified starch, proven to be much more effective than silica gel and desiccant clay.
- PREVENTS MOULD, DAMP & CONDENSATION in spaces prone to high levels of humidity. Prevents subsequent damage and corrosion to products, homes and spaces. Seadry anti-humidity desiccants can reduce relative humidity levels to as low as 50%. Absorbed moisture is then bound in gel form within the sachet so no chance that it will leak.
- USE IN ANY SPACE – Seadry container desiccants have been designed to reduce moisture in containers to protect cargo, however they can also be applied in the home or business to reduce humidity levels in any enclosed space. Amount of desiccant required will depend on the application, size of space and humidity levels throughout the journey/required time period.
- SINGLE DESICCANT SACHET contains 1 x desiccant sachet with adhesive strips (Comes in a pack of 5). One sachet is capable of absorbing more than 0.25l of moisture!

## Questions & Answers

**Q: Will  this be effective in a transit size van full of 5L bottles of liquid chemical? I have a lot of condensation issue due to volume of liquid**
A: Yes it will but make sure you buy enough of them. I had 4 in a steel storage container

**Q: Are they reusable and how do you dry them out.**
A: They are not reusable and will last approximately 3 months depending on the environment. They cannot be dried out they have to be deposited at the local recycling centre. We used it in our beach but everything was kept dry not a sign of damp, mildew or mould since we put it in at the end of Ice beginning of November and replaced it last week

**Q: What are the dimensions of the various products?**
A: I am sorry but I don't know the dimensions. I can't even tell you how good the product is as I put two in my small Campervan and parked it up for the winter while I go home to New Zealand. I will put a review after I get back in mid June.
T

**Q: How many poles would be required for a standard 20ft container? And over an English winter how long would they last/need repacking?**
A: We recommend 6kg of desiccant for a 20ft container which is equivalent to 4 x our ‘Blanket’ type container desiccants. 
Their lifespan will vary based on conditions over the winter and whether the container will be opened regularly or not. 
The minimum time lifespan is 6 weeks, but they could last up to 3 months if there was low humidity and the container was kept closed. 
However, they can be checked regularly after 6 weeks to see if the packets are full and if they require repacking.
